Problems solved by technology

[0003] At present, there are no automobile companies in China that manufacture active stabilizer bar systems, and they do not have the ability to independently develop them. The stabilizer bars of domestic cars are generally passive, and the ability of this type of stabilizer bar in anti-roll is very limited, especially for For off-road vehicles with a large degree of roll, the passive stabilizer bar is even more difficult. Therefore, in terms of safety and comfort, it is far from meeting the requirements of the active stabilizer bar.
Only some universities and other research units have done some research in this area, but they have not made breakthroughs.

Abstract

The invention discloses a control system and method of an electric active stabilizing rod. The control system is characterized by comprising a control unit, a gyroscope sensor, a rotor position sensor and a current sensor; the control unit comprises an attitude detection circuit, a motor rotor position signal processing circuit, a current sampling circuit, a motor vector drive and overcurrent protection circuit and a master control chip. The sidesway angle of a vehicle can be controlled in real time, and therefore during vehicle high-speed steering, the driving safety and taking comfort of the vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a control system and a control method for an electric active stabilizer bar. Background technique [0002] With the continuous increase of vehicle speed, people have put forward higher and higher requirements for vehicle ride comfort and safety, but conventional passive suspensions with passive stabilizer bars are difficult to satisfy ride comfort and handling stability at the same time In addition, it is impossible to adjust the roll angle stiffness of the suspension in real time. When turning at high speed, the vehicle is prone to roll, and excessive roll will easily cause fatigue and insecurity to the driver. Therefore, the research on vehicle active anti-roll control is one of the hot research issues in the automotive field. [0003] At present, there are no automobile companies in China that manufacture active stabilizer bar systems, and they do not have the...
